World number one Rafael Nadal crushed 17-year-old Australian hope Thanasi Kokkinakis in straight sets to reach the Australian Open third round in steaming Melbourne.
The Spaniard was kept on Rod Laver Arena for one hour and 53 minutes before winning 6-2, 6-4, 6-2 against the 570th-ranked Australian.
The top seed broke Kokkinakis's serve five times and saved the three break points against him in a routine victory for a player chasing a 14th Grand Slam title and his second Australian crown after winning in Melbourne in 2009.
Nadal smashed 39 winners, seven aces and dominated with his powerful forehand.
“Very glad,'' said Nadal when asked if he was happy the stadium roof was closed after the tournament's Extreme Heat Policy was enforced after temperatures soared over 40 degrees Celsius. –AFP
